SPECIFICATION forming part of Letters Patent No. 290,832, dated December 25, 1883, Application filed July 9, 1883. (No model.)

To aZZ whom it may concern.

Be it known that 1, CHARLES G. ANDERSON, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Chains; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- I Figure l is a top view of two of my chainlinks coupled. Fig. 2 is an end view of one of the links, showing the interlocking teeth of the end bars coupled. Fig. 3is atransverse section through Fig. 1 in the line 00 00, showing the inner side of the end bars coupled. Fig. 4: is an inside view of one of the side bars,showing an end view of its end bar. Fig. 5 is a side view, partly in section and partly in full and dotted lines, showing the position in which the side bars and their end bars should be adjusted preparatory to locking the end bars. Fig. 6 is a perspective view of one of the side bars of a link and its end bar.

' This invention relates to what are denominated divisiblechain-links, and it consists in a novel improvement on the chain for which Letters Patent No. 271,186 were granted to me,bearing date January 28, 1883, which improvement will be fully understood from the following description, when taken in connection with the annexed drawings.

The side bars and coupling-bars composing the links of a chain are precisely similar in size and construction, for which reason a particular description of one link of a chain of any length will suffice to give a clear description of all of the links composing the chain. The links are practically rectangular, although they may be of any other suitable shape, and when taken edgewise they may be made tapering, or their parallel bars may be made of an equal thickness from one end to the other. Each link is composed of two longitudinal section or side bars, A A, and each section or side bar is constructed with a transversely-perforated eyepiece, B, on oneend, which is in thickness about one-half the space between a link. The eyepieces B B of one link are adapted to fit snugly together and play freely between the ends of another link, to which the former is coupled, so that the chain will be of an equal width throughout. Those ends of the side bars, A A, which are opposite the ends having the eyepieces B B formed on them are constructed with cross-pieces G O, which are locked together in the eyepieces of another link, forming a pivotal coupling for the two links. Each cross-piece 0 may be cast with its side bar, A, or it may be formed separately andriveted or otherwise secured to said bar. The crosspieces 0 have short cylindrical portions a a, transverse grooves b, and a semi-cylindrical portion, 0, or tooth, the flat surface of which is oblique to the longitudinal plane of the top and bottom edges of the side bars. These toothed cross-pieces form interlocking pivotal couplings for the links, and it willbe observed that when they are coupled the oblique tooth c of one piece is received in the recess of the other cross-piece. Owing to the obliquity of the semi-cylindrical portions 0, the side bars, A A, must be adjusted at an angle to each other, as represented by Fig. 5, in order to interlock them in the eye-pieces of a link to effect a coupling, and also to disconnect one link from another. After the two cross-pieces G C of one link have been introduced into the eyes of another link, the coupling is effected by moving the side bars, A A, in one plane, which adjustment causes the teeth 0 O to in terlock.

It is obvious that when the side bars of the links are locked and coupled they cannot be separated, except by adjusting these bars in the same angular position described for coupling them.

If any one or more of the side bars of the chain-links should break,such bar or bars can be readily detached from the unbroken sections and new sections substituted.

Y Having described my invention,whatI claim as new, and desire to secure by Letters Patent, 1s-

A chain composed of longitudinal sepa- In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
